VANCOUVER, June 5, 2017 /CNW/ - Leading Edge Materials Corp. ("Leading Edge Materials") or ("the Company") (TSXV:LEM) (OTCQB: LEMIF) is pleased to announce additional high grade lithium results from a further seven diamond drill holes at the Company's 100% owned Bergby lithium project in Sweden. Furthermore, re-assay results from the first five drillholes reported 25thApril 2017 are also provided, which has on average increased the grade of lithium mineralized intersections for these holes.

Key Results:

•

BBY17006 intersected

4.45m @ 1.44% Li2O (lithium oxide) from 11.55m depth

•

BBY17007 intersected

4.65m @ 2.71% Li2O, 315ppm Ta2O5 (tantalum oxide) from 1.40m depth

•

BBY17008 intersected

8.75m @ 2.63% Li2O, 186ppm Ta2O5 from 1.10m depth

•

BBY17009 intersected

1.20m @ 2.68% Li2O from 14.80m depth; and

1.10 m @ 2.44% Li2O from 24.55m depth

•

BBY17010 intersected

8.80m @ 1.11% Li2O, 98ppm Ta2O5 from 27.55m depth

•

BBY17011 intersected

6.75m @ 1.87% Li2O, 191ppm Ta2O5 from 0.70m depth

•

BBY17012 intersected

1.65m @ 1.14% Li2O from 2.20m depth

Following a review of assay values for lithium reference standard samples within the batch of analytical results for drillholes BBY17001 to BBY17005 as reported 25thApril 2017, assay contractor ALS Ltd were requested to complete a re-assay of all samples using a technique better suited to high lithium grades.

Grades increased significantly for three holes, and decreased slightly for two holes, as follows:

•

BBY17001 intersected

1.45m @ 0.77% Li2O from 4.85m depth (26% increase from 0.61% Li2O)

•

BBY17002 intersected

3.95m @ 1.83% Li2O from 0.00m depth (24% increase from 1.48% Li2O)

•

BBY17003 intersected

8.20m @ 2.06% Li2O from 2.85m depth (34% increase from 1.54% Li2O)

•

BBY17004 intersected

1.90m @ 2.26% Li2O from 10.20m depth (3% decrease from 2.35% Li2O)

•

BBY17005 intersected

10.45m @ 1.58% Li2O from 2.20m depth (3% decrease from 1.62% Li2O)

Blair Way, President and CEO, stated "The Bergby lithium project continues to deliver very encouraging high grade drill results at very shallow depth. Mineralization has been discovered in every drill hole to date, and we look forward to advancing the prospect quickly from here. In addition to lithium, regular elevated grades of tantalum are also being discovered. While the need to re-state drill intersections due to assay accuracy is always frustrating, the increased average grade for the first five drill holes is a worthy reward."

Bergby lies in central Sweden, 25km north of the town of Gävle, secured by three exploration licenses that cover a total of 1,903 Ha. The site is close to infrastructure, with major roads, rail and power supply passing immediately adjacent to the claim boundaries.

Holes reported within this release lie within a 150m x 80m area near a lithium mineralized pegmatite outcrop. Mineralization drilled to date lies very close to surface, and extends from the outcrop beneath thin glacial soil cover. Intersections often include elevated levels of tantalum (see Table 2 for all mineralized intersections).

The true thickness of the mineralized interval is interpreted to be approximately 90% of the sampled thickness. Further drill results will be released as they become available.

Europe is playing a leading role in the transition to low-carbon energy generation from renewable sources, and the efficient storage of that energy. Electric mobility (EV's, HEV, PHEV's) and stationary electricity storage are dependent on high purity graphite, lithium and cobalt, where Leading Edge Materials is an active European player. Lithium has a strong and expanding market, due to the essential role it plays in lithium-based batteries for the automotive, consumer product and stationary electrify storage industries. The high electrochemical potential of lithium results in the high power to weight ratio that is essential for efficient mobile batteries.

On behalf of the Board,
